DEVICE FOR DISTRIBUTING AND EQUALIZLNG POWER.

SPECIFICATION forming part of Letters Patent No. 602,087, dated April 12, 1898.

I Application filed May'lo, 1897. Serial No. 635,959. (No model.)

To rtZZ whom it may concern:

Be it known that I, RUSSELL MARVIN, a citizen of the United States, residing in the city of Findlay, Hancock county, and State of Ohio, have invented new and useful Improvements in Devices Adapted to Receive, Equalize, and Distribute Power from any Suitable Generating-Motor, of which the following is a specification.

The particular object of my invention is to provide a power-distributor for the purpose of pumping from a common point of application a number or cluster of oil or other wells by means of surface-rods or other similar devices, and by means of such distributer balance and equalize by a proper application of gravity the separate resistance to be overcome in the several wells, thereby economizing the otherwise necessary expenditure of power, and touse the gravity and frictional resistance of any particular well in such cluster when the same is not being pumped to anchor the said distributor against the otherwise unbalanced strain of the wells being at the time operated. I attain these objects by means of the mechanism illustrated in the several drawings hereto attached and hereby made a part of this specification.

Throughout the several views like letters refer to identical or like parts.

In the said drawings, Figure 1 is a sectional view on a vertical plane through the line U V in Fig. 2, including an eccentric device not shown in Fig. 2. Fig. 2 is a plan view from above, on a smaller scale than Fig. 1, showing all the parts visible fromthat point except an eccentric above referred to, and hereinafter described. bearing of a counter-shaft D shown in the preceding named figures. Fig. 4 is a view of the under side of a terminal bearing-cap c;

' and Fig. 5 is a corresponding view of the upthe several parts of the bearing of the shaft 0. Fig. 8 is a view of the under side of a ring I, which in position surrounds the eccentric wheel H, as shown in Fig. 1. Fig. 9 is a Fig. 3 is a detail of the end and plan view of a bed-piece A, which is a foundation to my entire device.

I construct my device of the several parts illustrated in said drawings, as follows: I provide first a substantial and solid frame, preferably in a tripod form, consisting of a bedcasting A, (shown in Figs. 1, 2, and 9,) said bed having arms or spokes running to its center and there supporting a suitable socket a to receive,with an antifriction-roll and ballbearing, hereinafter particularly described, a central vertical bearing-shaft C, said bed A also, at points a a, being webbed in suitable form to receive the journal-blocks cl d of a horizontal counter-shaft D. Securely bolted to points marked a are three posts or risers B, so curved inwardly'as to meet about the vertical axis of socket to at a suitable distance above it to receive an antifrictional roller-bearing as a lateral support for shaft 0, the upper ends of posts B so meeting having concaved'ends b and flanges b, adapting the posts B to be fastened together by bolts or other suitable devices, and when so bolted together forming bytheir concave ends I) a journal-block to contain said bearing for shaft 0. To make the frame more rigid and to assist in the anchoring of the same, as

hereinafter mentioned, I bolt or securely fasten to posts B, either cast entire or in suitable segments, the ring E, perforated at intervals with holes e. (Shown in Figs. land 2.) Bed A is also provided with perforations a to allow it to be anchored by bolting to suitable mudsills or by stakes in the earth.

Within the socket a and the concave ends to fit said balls 0, exactly corresponding to groove 0. The upper side of cap 0 is recessed in any suitable manner to receive and hold I the lower end k of shaft 0, which is fitted to such recess.

' In socket a, above and resting vertically on bushing is formed by bending a thin sheet of scr ws-' 9". ycessrun drilled, screws Pmay end in bu shin g j plate 0, is a lateral roller-bearing for shaft '0, formed as follows: Immediately "about shaft 0 and cap 0 are a series of vertical rollers resting and rotating on their lower ends on plate 0'. Rolls 0" are confined to position by, first, a bushing 3, preferably of tempered steel, though it may be of any material sufficiently hard enough to stand the Wear. This said metal to Conform to the periphery of said rolls 0 about 0, the ends of such sheet being so cut as to meet accurately and on a bias or diagonal to the vertical, as shownin Fig. 6. The thin hard bushing s is immediately inclosed by a heavy ring or bushing s to make the entire journal solid and firm; but bushing 8' may be of a soft iron or other metal suitable forec'ono'mical Workin g. The height of bushings s and san'd rolls '1" are the same. Any remaining space between 8 and the mu 5 of socket a is filled with a Babbitt or other suitable packing metal, so that when com plete thewh'ole will be as solidas if cast in one piece. Theseveral p'a'rtsof this journalviz.,the babhitting and bushings sand s' are made-more fiimahd held in proper adjustment by screws p, which pass through the said parts and by which the proper vertical ad ji'iistrnent of bu s'hin'g'ss ai1d scan be effected before said babbitt is applied, so that 'when the babbitt is. fiiled in "between socket a and bushings it will by its adhesion prevent the loosening of If bushing sis too hard to be sucs and bushing s be kept in place by screws or bolts 19", screwed into the upper end of bushing 8 close enough to bushin'gs that the heads projec'tover and prevent it from wor ing up, if it haves'u'ch tendency.

drawings the same.

'lhelateral bearing within the concave ends b of B is in all respects similar to the one in;

socket a, except that at the lowerend a plate 'qis closely fitted to shaft 0 to support the. rolls and bushingsa'nd to retain l ubricator.- The 'pl-ateq may be conveniently bolted to the L in'de'r side of theends 'b of posts Since this upperjournal of shaft O is identical, asstated, with the lower'one, except as noted, I have lettered the like parts thereof in'the:

These bearin gs are in all respects similar to the lateral bearings of'shaft O, al- 're'ztdydescribed, except as the blocksd are; 'easilyhaiidled for Work, 850., the bushing s" and'the babbitt used about'it'are'emitted andthe block cl itself immediately holds the bushing sand the rolls 1", which throughout the drawings are lettered as are the parts of the journal of shaft 0. The said journals of D are provided at either end with the plates q.

Above the bearing at the upper end of posts B shaft 0 carries an eccentric device consisting of an eccentric Wheel H, solidly attached to shaft 0, provided upon its lower side with afiange h, adapted to support and carry upon suitable travelers on a loosely-mounted nonrotating inelosing ring I and to support and carry upon said flange h and between its perimeter h and the perimeter 't' of ring I a bearing consisting of a series of vertical rolls r, separated at intervals into sections by rectangular shoes Z, said ring I having suitable holes 4: or lugs to or other suitable means of attachment for surface-rods, said eccentric device being, except as to the use of shoes Z, in all respects simi-lar to the eccentrie'de'vice described by me in my application for patent for eccentricdevices filed in the United States Patent Office July 1', 1895, Serial No. 554,665.

' Said shoes "Z are of slightly less diameter than the rolls r and of the same height, but of breadth about equal to twice the diameter of thesame,-ai1d at the edges either plane or concaved to conform to the rolls 'r', the reasons for which I hereinafter specify.

My power being so constructed as above described and hash-area, its operation for the purpose named is as follows: Being suitably located 'with reference 'to the 'wel'ls 'to be pumped, preferably near the center of the group, the wells are attached to ring I of the power by suitable connection, as by surfacerods, care being taken in attach-ingtothe various points of ring 1 to balanceas far as pos- "sible the gravity and frictional resistance of the several wells, so thatas nearly as possible equal power may be required throughoutja revolution. Power is eommurricated't'h rough counter-shaft D and 'Wheels'G and F andshaf t O to the eccentric H by which an oscillatory motion is communicated to ring I and by it, through surface-rodsandsuitableconiiecting mechanism, reciprocating motion "to the well operated.

When for any reason it is desired to stop the *ac'tionof'one or more wells while the balmice is operated, the rods connecting such wells with I should 'be disengaged from -T'and {attached to ring E, as "the gravity and 'fr'ietio'nal resistance of the well not operated become ananchor to the power and a counterpoise to the strain from other directions by the wells still being pumped. Ring E thus serves thedouble pu'r pose ofmaking-the posts Brigid and of anchoring the entire power against unequal lateral strains.

Someof the-advantages of "the mechanism described and illustrated for the purpose specified'are as follows: Accliracyof adj ustinenueconom of construction and repair, mechanical convenience in repairing or re- 'newing parts, and economy-of power in operation.

It is practically both inconvenient andexpensive in heavy and irregular-shaped castings, such as are necessary in forming theframe to my power, to turn and plane the castings to perfect alinement and exact didiate bearing to the shaft and making thewhole solid by the set-screws and any suitable packing.

Should at any time the bushing 8 become worn' too much and need replacing, it may be removed and another inserted in its place without the inconvenience of removing the shaft or even of raising it temporarily from its bottom hearing, as the bushing made, as described, of a thin sheet of metal can be sprung open and so placed about the shaft.

This is an important advantage as to the up-' per bearing especially, as it comes between the solidly-attached wheel]? and the eccentric H, so that without the device of the open bushing one of these wheels would have to be removed from the shaft to replace the part. This bushing s, as also the terminal cap 0 to shaft 0 and the bearing-plate 0', may be tempered exceedingly hard, so as to greatly resist ordinary wear, without the expense and inconvenience of so tempering and working the larger and heavier parts, and should the bearing at the bottom of shaft 0, formed by the cap 0 and plate 0 and the balls 0 between, become by wear or breakage or otherwise out of order they may be easily repaired and replaced by duplicate parts by simply temporarily raising shaft 0 andremoving the lat-- eral bearing in socket a.

The method of controlling the j ournal-blocks d, holding the bearings of the shaft D, is also a great advantage, for by their means not only may leveling and alinement be rectified within certain limits, but perfect adjustment may be made of the wheels F and G and Wear thereon compensated.

Experience has shown that in the use of a roller-bearing about a large perimeter, as that of eccentric H, when the rolls are placed in.

normal vertical position with su flicient practical working space between them to obviate binding, &c., that by the wear'and friction of revolution they have a tendency to get into positions diagonal to their normal vertical position, thereby creating a large amount of unnecessaryfriction and consequent loss of power. By inserting in such a series of rolls shoes Z, thereby dividing the series into sections of such a size that the aggregate of wear and working space does not allow opportunity for any great degree of tipping of the rolls of that section or the communication of such tipping to other sections, this tendency is overcome, and the small amount of friction caused by the insertion of such shoes is unnoticeable.

It will be noticed thatthe mechanism above illustrated is applicable both for the purpose specified in the form described and in modifications of it that will be at once suggested to any machinist or mechanic for many other applications. I do not therefore confine myself to the forms or parts as described, nor to specific arrangement beyond those mechanically necessary to accomplish the objects stated, but expect to use the same with such modifications as may be desirable without departing from the spirit of my invention for all purposes to which the same may be applicable. I

I am aware that eccentrics with encircling non-rotating rings upon vertical shafts for the purpose of developing and communicating oscillatory motion and converting the same into reciprocal motion have been in use publicly for some time and to some extent with roller-bearings between such eccentric and ring and that thesame are in use for the purpose of distributing and equalizing the application of power in the pumpingof oiland other deep wells. I am also aware that both ball and roller bearings are widely used in the transmission of mechanical power in manyforms and that some other features of the mechanism I have described are in use and known for other purposes. I do not herein, therefore, broadly claim any novelty in the use of such devices; but,

Having above described my invention in all its parts,'so that any skilled machinist may build or operator use the same or any suitable modification of it, what I claim as novel, and desire to secure byLetters Patent,
